D5801
1. D5801 is an 8 clone synthetic variety. Its parents trace back through several intermediate steps to: Tempo, Answer, Apollo, Iroquois, Teweles Multistrain, MSB, MND-P1 and Dairyland experimentals. Dairyland experimentals trace to Ranger and Vernal. Parent plants were selected out of forage yield plots and progeny tested for one or more of the following traits: Forage yield, stand persistence, winter hardiness, seed yield, and resistance to bacterial wilt, Fusarium wilt, Phytophthora root rot, anthracnose, Verticillium wilt and Aphanomyces. The percentages of germplasm sources are: M. falcata (5), Ladak (15), M. varia (10), Turkistan (10), Flemish (50) and Chilean (10).
2. D5801 is intented for use in the upper midwest and northeast region of the United States for hay, haylage, greenchop and dehydration. The states where it has been tested are Wisconsin, Iowa, Illinois and Michigan.
3. Flower color in the Syn. 2 generation is 74% purple and 26% variegated, with trace amounts of cream, white and yellow. Growth habit in mid-summer is erect and semi-erect in the fall. Its fall dormancy is similar to the variety Saranac.
4. DS801 has high resistance to bacterial wilt, Fusarium wilt and Phytophthora root rot and resistance to anthracnose (Race 1), Verticillium wilt and moderate resistance to Aphanomyces and spotted alfalfa aphid. Its reaction to pea aphid, blue alfalfa aphid, and stem nematode has not been tested.
5. Breeder seed has been produced from cuttings of the parental clones in an isolation block as Syn. 1. Enough Breeder seed (Syn. 1) was produced for the expected life of the variety. Seed lots will be kept separate. Foundation seed will be produced from Breeder seed and Certified seed from either Breeder or Foundation seed. One generation each of Breeder and Foundation and two generations of Certified seed classes are recognized. A maximum of three years each is permitted on stands producing Breeder and Foundation seed with five years for Certified seed.
6. Certified seed will be available the spring of 1991.
7. Application for the Plant Variety Protection is undecided.
8. As a means of additional varietal protection, information included with this application may be provided to the PVP office.
